Specifying output schema for a UDF returns a tuple has been changed

Before 0.12, There are two ways to specify tuple output schema for a UDF:
1. Returning a schema contains a single tuple field
2. Returning a schema that containing more than one field and it will be understood as a tuple schema
However, the second way is not reliable. It sometimes works and sometimes not. So in 0.12.0, we drop the second way and only the first way works.

rpm and deb package no longer available

Starting with Pig 0.12, Pig will no longer publish .rpm or .deb artifacts as part of its release. Apache Bigtop provides .rpm and .deb artifacts for Hadoop, Pig, and other Hadoop related projects. See Bigtop's how to install page for details.
